Soft Drinks 15 diet colas 4 cans of lemonade 6 cans of root beer 25 TOTAL (a) PROBABILITY OF NEXT DRINK TO BE Formula Discription Example diet colas 60.00% "=no of diet colas/total" "=B3/\$B\$6" cans of lemonade 16.00% "=no of cans of lemonade/total" cans of root beer 24.00% "=no of cans of root beer/total" (b) Classical Definition of Probability Imperical or Relative Frequency Definition of Probability Subjective Definition of Probability Formula Calculation You will need to pick only one of the three definitions, that is most appropriate, then de
elete the other two:
Coins Sample Space Possible Outcome Coin 1 Coin 2 Coin 3 Probability 1 T T T 12.50% 2 H T T 12.50% 3 H H T 12.50% 4 H H H 12.50% 5 T H H 12.50% 6 T T H 12.50% 7 T H T 12.50% 8 H T H 12.50% Each time a coin is dropped it will be either a Head H or a Tail T So one possible out come is that all coins show a Tail T: T T T, or first and second coin show a T w The probability for each out come is equal to the frequency of the outcome divided over the total time, so its probaility = 1/8 = 0.125 or 12.5%
while third coin show a Head H: T T H, and so on number of outcomes; for example T T T can only occur one
